Kiyoomi had lived his whole life as a beta. He didn’t present with his peers, not even with Motoya, who presented in his late teens. His parents never saw the need to make him see a doctor, and he didn’t care enough to visit one the older he got. If he presented good for him, and if he didn’t that’s good too.
He never saw being a beta as a bad thing, like many people did. He just went on about his life; he was actually thankful for being a beta. Ruts and heats all seem like such a hassle to him, especially when they are as rough as his older brother’s heat or Motoya’s ruts.
That was until he joined MSBY and met Meian Shuugo, captain of the MSBY Black Jackals. He was one of the most reliable people he had ever met and an alpha. It wasn't just his status as an alpha who always had omegas all over him; it was his whole self. He was attractive, caring, attentive, warm, and soft.
Kiyoomi would never get a chance with him. His captain had always taken omegas to accompany him during the night and sometimes even as rut partners. And as a beta, he could never offer what the older man deserved. At least that’s how Kiyoomi saw it.
It wasn’t until a few years after joining the team that Kiyoomi started to change. It was subtle at first. It started with body aches that he attributed to his hypermobility and career as an athlete. Then it was the new scents he could pick up from his teammates. One by one, the smell of his teammates started changing. Kiyoomi always thought they had started trying new products for themselves, perfumes, soaps or even detergents. He paid it no mind until Hinata commented on it.
“I’m not sure what you’re talking about, Omi-san,” Hinata had pondered when Kiyoomi asked about the tropical and citrusy scent he recently smelled on the other.
“Are ya feeling alright omi-kun?” Atsumu, ever in tune with his spikers, interjected, “Ya haven’t been looking’ too good.” Kiyoomi had brushed his concerns away. He shouldn’t have, Atsumu was never wrong in his assessments. Kiyoomi had walked out of the locker room with the heavy gaze of his captain on his back. The next day he called in sick to practice.
“So suddenly?” Foster’s concerned voice came through the speaker, “You seemed quite alright yesterday.” His coach’s voice was barely above a whisper.
“Would you like me to tell the team?” Kiyoomi, tired like never before, had muttered a small, “Alright.”
“Take care of yourself, kid,” with those parting words, Kiyoomi hung up.
Kiyoomi spent most of the day going in and out of sleep, only standing to eat some light food and go to the bathroom. Later in the evening, he was awoken by a knock at his door. Dragging himself off his bed, bringing his fluffiest blanket with him, he headed towards it. Upon opening it, he found the blonde omega setter carrying various bags with him.
“Ya look like shit Omi,” Atsumu invites himself in, quickly kicking his shoes off and continuing inside.
“Thanks,” Kiyoomi drawls, plopping on his couch.
Atsumu takes Kiyoomi’s state in for a few minutes before sitting beside him. The raven-head instantly settles against his side. Atsumu started pumping out soothing pheromones, well aware that Kiyoomi couldn’t pick up on it. Or so they both continue to think. Kiyoomi falls into a peaceful rest.
In the following months, all his teammates were more attentive to him. They all noticed the small changes in Kiyoomi. From the way he now followed with his nose first, to his heating up at random times.
The most notable change was how Meian acted around him. He was always hovering near Kiyoomi. A hand always close or touching him, supportive and caring. Trouble rose one night the team went out. Kiyoomi had been chatting with Atsumu and Inunaki when an alpha approached both omegas, ignoring Kiyoomi’s existence with them.
When Kiyoomi interferes, the alpha’s attention now fully on him. The alpha had smiled something nasty, crowding Kiyoomi’s space and making his hackles rise. Not long after, Meian had appeared by his side, hand possessive on his waist, bringing him against his side.
“This one yours?” The unknown alpha asked with a smirk, “Why don’t you let me have him for a night, I’ll pay you for it.”
The following moments were a blur of snarls and punches. Bokuto and Tomas pulled Kiyoomi and the two omegas away from the fighting alphas as other members of the team pulled Meian from the other alpha. Later in the night, they all received an apology from their captain for his actions.
A week after that fiasco, tensions broke as Kiyoomi fell in the middle of practice. The gym seems to freeze as they all watch the spiker crumble to the ground. A new, sour, and fruity scent takes over the whole place. Next thing they knew, all the alphas were trying to reach Kiyoomi. None managed to get close. Not with Meian over Kiyoomi, who was whimpering and pumping out distressed pheromones.
Meian growled and snarled at all the alphas who tried to get close to them. Snarling at Bokuto, mated and very much taken, who tried to bring some sense to the captain. To the omegas trying to get Kiyoomi away from all the affected alphas.
“Fuck you,” Atsumu snapped when Meian growled at him for getting too close. The blonde continued to get closer, letting out his own growls as Meian kept him away from the blooming omega.
“Atsumu,” their coach had called, “Be careful.”
Atsumu, with the confidence only a setter who knew their spikers could muster, grabbed both Meian and Kiyoomi, sure to keep them as close as he could, and ushered them to the locker room. Kiyoomi latched to Meian with no intention of letting go. Whining and whimpering against the other.
“Ya better take care of him,” Atsumu threatened as he grabbed both their bags, “If I find ya hurt him, I’m going after yer dick.” He gritted with a cold gaze.
The alpha stared back at him, nodding firmly, now calmer with just the other omega near them. An omega he knew Kiyoomi cared about and was the closest with. Satisfied, Atsumu hauled both gym bags and ushered Meian, who was carrying Kiyoomi at this point, to his car and drove to Kiyoomi’s place.
Once in the safety of his home, Kiyoomi relaxed for a second before intense heat coursed through his body. His new, potent scent, soured further, sending the alpha into a panic.
“What do you need,” Meian’s tone was gentle as he scented the newly presented omega.
“You,” Kiyoomi barely got out, “Need you, Alpha.”
Meian growled lowly, possessive of the omega in his arms, “Anything for you,” he whispered against Kiyoomi’s lips.
Kiyoomi gazed at him with teary eyes, surging forward to capture his captain's lips, mewling in delight at the taste, at the feeling against his lips against the other. Soon they found themselves on Kiyoomi’s bed. Meian was as soft and careful as he could be with Kiyoomi. Helping him through his first heat.
When Kiyoomi’s heat ended, they walked hand in hand inside the gym. The other guys hollering and whistling at all the marks they saw littering Kiyoomi’s body as he changed. Only to silence themselves when they saw Meian’s state.
“Possessive bastards,” Inunaki muttered. Atsumu smirked, heading to Kiyoomi to get all the juicy details.
